资源简介：
The usage of heat absorption water-ammonia refrigeration units in atmospheric water generation sys-tems is considered. A basic design of periodic operation AWRU is described. A method for thermodynamic calculations and analysis of AWRU PO cycles and modes of operation is presented. Specific refrigerating capacity depending on the composition of water-ammonia solution, the temperature of the heating source, the ambient temperature of the environment is calculated. It is shown that increasing the temperature of the heating source from 65°C to 95°C leads to minimum temperature in the cooling zone decreasing from 7°C to -17°C. Low-temperature ambient air at 25°C enables attaining the maximum value of refrigerating capacity of AWRU PO by increasing the proportion of ammonia in the initial composition from 0.3 to 0.5, and this enables lowering of the heating temperature from 95°C to 65°C.
